Does this mean we're going to see music FRP examples soon?!

Dear list,
the Show class is extremely useful for exploring Haskell in a terminal, but sometimes, I just want something fancier. For instance, I'm currently dabbling with sound generation and it is only natural that I want to hear the sound instead of seeing a textual representation. Another example would be graphics, that are simply drawn on screen whenever you evaluate their value.
Of course, this is simple to implement with a class
class Demonstrable a where demo :: a -> IO ()
instance Demonstrable Sound where demo = play instance Demonstrable Sound where demo = draw instance Demonstrable GUI where demo = run etc.
However, I don't want to reinvent the wheel, small as it may be, hence my question: is there a package on hackage that already defines a class similar to Demonstrable ? Or any other projects in this direction, like, say, a fancy REPL built on wxHaskell?
Best regards, Heinrich Apfelmus
